Question

What are the various energy transformations that occur when you are riding a bicycle ?

• A. Muscular energy to kinetic and heat energy
• B. Mechanical energy to chemical and light energy
• C. Chemical energy to Internal energy
• D. Rotational energy to muscular energy

Answer 1

The correct option is A Muscular energy to kinetic and heat energy

While riding a bicycle,the muscular energy of the rider gets transferred to heat energy and kinetic energy of the bicycle.Heat energy heats the rider's body.Kinetic energy provides a velocity to the bicycle to move in rotation.The transformation can be shown as:
Muscular energy$=$kinetic energy+heat energy
During transformation,the total energy remains conserved.
